Peregrinus maidis on maize can oe controlled by several applica- 
tions of nicotine dust during the heat of the day. Lelons infested wit 
Aphis gossypi i should be dusted with nicotine dust or sprayed with 
nicotine sulphate (40-percent) at 1 to 300 plus a little soap during th< 
heat of the day. Nicotine dust may also be used to control Trialeurode 
(Dial eurodes ) vaporario rum (whitefly) on these plants.

sulphate( 1:800) . A. (?) sinensis Delg. on lilies is easily controlled 
by dusting with nicotine or spraying with nicotine sulphate.
